  • SUPRANITE PACKING 557

    SUPRANITE PACKING 557

    SUPRANITE ® PACKING 557 is an expanded graphite braided packing for valves, reinforced by Inconel ® wires in a specific structure that limits friction and improves the sealing performance. SUPRANITE ® PACKING 557 is manufactured from graphite tape reinforced by Inconel ® wires and specially treated with a corrosion inhibitor.

    • The low-sulphur graphite quality (<300ppm) of SUPRANITE ® PACKING 557 limits corrosion.
    • The particular structure of SUPRANITE ® PACKING 557 allows its use alone as a complete sealing set of rings or just as top and bottom rings with SUPRANITE ® NGN 02 AS moulded rings.
  • SUPRANITE PACKING 557 EF

    SUPRANITE PACKING 557 EF

    SUPRANITE ® PACKING 557 EF is constructed from exfoliated graphite tape reinforced with a specific Inconel ® mesh, treated with a graphited lubricant reducing frictions and a corrosion inhibitor.

    • The specific braided packing developed for effective valve fugitive emission reduction.
    • Certified ISO 15 848-1 in simple product assembly due to its exceptional sealing performance
    • Specific structure ensures high integrity under high sealing stress associated with very low friction
    • Can be used directly from the coil or in preformed rings without anti-extrusion rings, which facilitates its implementation.
  • SUPRANITE PACKING 251 VR AS

    SUPRANITE PACKING 251 VR AS

    SUPRANITE ® PACKING 251 VR AS is a packing core of expanded graphite Supranite NGN 02 AS (PMUC N°17-0077) reinforced by Inconel and overbraided with special pure ptfe yarns. The free lubrification composition severely limits creep and loss of mass in service.

    • SUPRANITE ® PACKING 251 VR AS is the reference for PMUC braided packing used in nuclear power control valves.
    • It has been fully approved PMUC at 90 Bars and 280°C (PMUC N°17-0019) in sets with top and bottom rings in SUPRANITE ® PACKING 242 CP AS (PMUC N°17-0170).
    • SUPRANITE ® PACKING 251 VR AS releases no corrosive chemicals up to 300°C, according to tests performed by EDF-GDL.
  • SUPRANITE PACKING 242 CP AS

    SUPRANITE PACKING 242 CP AS

    SUPRANITE ® PACKING 242 CP AS is composed with an expanded SUPRANITE ® NGN 02 AS (PMUC N°17-0077) graphite tape reinforced with Inconel ®. The reinforced yarns are then braided to produce SUPRANITE ® PACKING 242 CP AS.

    • SUPRANITE ® PACKING 242 CP AS is approved by EDF for top and bottom rings for valve stem sealing set (PMUC No. 17-0170).
    • After precompression, the small thickness of the SUPRANITE ® PACKING 242 CP AS rings allows a larger effective seal height and limits friction.
    • Made of SUPRANITE ® NGN 02 AS graphite, SUPRANITE ® PACKING 242 CP AS limits corrosion thanks to very low sulphur and halogens contents.

DYNAMIC APPLICATION PACKINGSDYNAMIC APPLICATION PACKINGS

  • SUPRANITE PACKING 530

    SUPRANITE PACKING 530

    SUPRANITE ® PACKING 530 consists of very thin filaments of spectroscopically pure PTFE. SUPRANITE ® PACKING 530 is impregnated, core and surface, with a PTFE dispersion that greatly limits the coefficient of friction and improves the sealing performance.

    • Made of only ultra-pure PTFE yarns.
    • Features outstanding chemical compatibility as it contains no other lubrification compound (oil,...) than pure PTFE dispersion.
    • Approved for use with oxygen.
  • SUPRANITE PACKING 545

    SUPRANITE PACKING 545

    SUPRANITE ® PACKING 545 is a packing made entirely of thin graphite filaments having a High Specific Modulus and high mechanical properties, coated with a thin film of PTFE to facilitate fitting and running in. The specific purity of the graphite filaments of which SUPRANITE ® PACKING 545 is made preserves the mechanical properties of the braided packing when it is exposed to high temperature, especially in the case of very high friction (extreme speed, over-tightening, etc.) or a lack of lubrication.

    • Chemical compatibility is greater than conventional graphite and carbon braided packing.
    • Each filament is coated with a very thin PTFE film to optimize running in and limit premature wear of the braided packing thanks to a low coefficient of friction.
    • Increases packing-box life in most applications.
  • SUPRANITE PACKING 602

    SUPRANITE PACKING 602

    SUPRANITE ® PACKING 602 is made from high-density diagonal braiding of two complementary synthetic yarns : one with high mechanical strength, while the other provides excellent self-lubricating properties and facilitates the dissipation of heat generated by friction.

    • Used on most dynamic applications, in the presence of the most varied fluids.
    • Recommended for its high mechanical resistance against abrasive and crystallizing fluids.
    • Limits friction in high-speed applications through its dual (liquid and solid) lubrication system.
    • PMUC approved (Products and Materials Usable in Power Stations) by EDF.
  • SUPRANITE PACKING 660

    SUPRANITE PACKING 660

    SUPRANITE ® PACKING 660 is a new grade of braided packing made from an innovative organic yarn that combines high mechanical strength and limits shaft wear, associated with a dry lubrication system that increases packing-box life.

    • An innovative organic yarn that is as strong as conventional aramide but limits shaft wear.
    • A new dry lubrication system that maintains a very low coefficient of friction between two maintenance operations.
    • Substantially longer packing box life in mechanically, thermally, or chemically aggressive media.

  • SUPRANITE PACKING 850

    SUPRANITE PACKING 850

    SUPRANITE ® PACKING 850 is produced by braiding pure calcium silicate yarn. The absence of an organic support in the production of these yarns results in a much smaller loss of volume at high temperatures than with most other products.

    • Covers all static sealing and thermal insulation applications with excellent resistance to temperatures up to 750°C continuous.
    • Low loss of volume at high temperature because of the unique composition - pure calcium silicate of the SUPRANITE ® PACKING 850. High mechanical resistance to abrasion, imparted by the size of its fibres.
    • SUPRANITE ® PACKING 850 exists in square, round, or rectangular shape braided packing but also in tapes or tubes shapes…
  • SUPRANITE PACKING V01

    SUPRANITE PACKING V01

    SUPRANITE ® PACKING V01 is made from chemically and thermically exfoliated vermiculite ribbons reinforced with Inconel ® mesh. This construction allows excellent handling characteristic, minimize extrusion under compressive load and improves blow out resistance.

    • Creates a gas tight seal at very high temperatures - up to 1,000°C.
    • Not subject to the oxidation of the graphite and has a very large chemical resistance range.
    • Reinforced by a specific Inconel ® mesh, SUPRANITE ® PACKING V01 is resistant to extrusion under high stresses, while remaining very flexible and easy to install.
  • SUPRANITE PACKING 801

    SUPRANITE PACKING 801

    SUPRANITE ® PACKING 801 is made of long pure amorphous silica filaments that do not loose weight and volume at high temperatures. SUPRANITE ® PACKING 801 is made of mass braided yarns, giving the product excellent mechanical resistance and ensuring a good seal.

    • Withstands temperatures up to 1,000°C continuous
    • Very great mechanical resistance to abrasion and stress
    • No loss of mass at high temperature, high density
    • Does not contain refractory ceramic fibres designated as carcinogenic by European directive 97/69/EC
  • SUPRANITE PACKING 650

    SUPRANITE PACKING 650

    Supranite Packing 650 is made with Supranite Packing 850 tape vulcanized for mechanical resistance and contains in its core the Supranite Packing 600.
